1 Claim. (o1. 81-86) This invention relates to a plier wrench, and it isan object of the invention to provide a tool of this kind which can beemployed in connection with pipes, rods or other round objects in amanner assuring a firm grip.

It is also an object of the invention to provide a tool of this kindincluding two jaw members one supported for endwise movement withrespect to the other, and wherein a handle member is pivoted to one ofthe jaw members and coacts with the second jaw member in a manner toimpose desired endwise movement to the movable jaw upon swinging of thepivoted handle memher A still further object of the invention is toprovide a plier wrench including two jaw members, one having endwisemovement with respect to the other, together with a pivoted handlemember carried by one of the members and coacting with the other forimposing endwise movement to said second member, and whereinspringpressed means are provided in association with the pivoted handlemember to hold the same normally in a position with the jaw members atthe limit of their relative movement one toward the other.

The invention consists in the details of construction and in thecombination and arrangement of the several parts of my improved plierwrench whereby certain important advantages are attained, as willbe'hereinafter more fully set forth.

In order that my invention may be better understood, I will now proceedto describe the same with reference to the accompanying drawing,

wherein:

Figure 1 is a view in side elevation, with por- Figure 3 is afragmentary sectional view taken substantially on the line 33 of Figure2.

As disclosed in the accompanyin drawing, l denotes an elongated shank ofa jaw member A which is provided at its outer end with a laterallyextending and relatively long gripping jaw 2 which coacts with asimilarly disposed gripping jaw 3 carried by the extremity of theelongated shank 4 of the second jaw member B. The shanks I and 4 are inclose contactso that the jaw member B may be readily moved into open orreleased position and with equal facility returned to closed or grippingposition with respect to the jaw member A.

The shank 4 of the member B immediately adjacent to the gripping jaw 3thereof is provided with a rigid guide loop 5 disposed in a directionopposite to that of the gripping jaw 3 and through which the shank l ofthe jaw member A freely passes.

The inner face of the shank 4 of the jaw member B is provided along theupper portion thereof and from its outer or free end with the teeth 6with which are adapted to engage the teeth I carried by the head 8 of ahandle member 9. This head 8 extends between the rearwardly dis posedside plates l0 carried by the shank I of the jaw member A and pivotallyheld therebetween by the pin I I.

The teeth 1 of the head 8 constitute a straight rack and with the 'majorportion of the rack beyond the center of the pivot pin II. The insertedend face l2 of the head 8 is arranged on a curvature concentric to thepin H and on such radius to be free of the teeth 6 of the shank 4 whenthe handle member 9 has been swung outwardly approximately a quarterturn to allow a quick adjustment of the jaw member A with respect to thejaw member B.

As the handle member 9 is swung inwardly toward the jaw member B, ormore particularly the handle member [4 thereof, the teeth I will againmesh with the teeth 6 and force the gripping jaw 3 of the member Btoward the gripping member 2 of the member A and thus assure effectivegripping of the work therebetween and more particularly when such workconstitutes a pipe, rod or other rounded surface.

The side plates H! are extended beyond the inner face of the shank I ofthe member-,B and formed to provide a guide loop l5 through which theshank 4 of the member B has endwise movement.

The outer extremity of the rounded face l2 of the head 8 has anoutstanding shoulder I6 with which contacts a fiat keeper ll, the outerportion of which has its under face rounded, as at I8, to closelyconform to the rounded edge face l2 of the head 8, so that the keeper llwill have a minimum of efficiency.

This keeper I 1 has its lower or inner portion received in the suitablyformed socket l9 provided in the end face 20 of the shank l between theside plates l0 and the lower end of this keeper IT, at its central part,is continued by an elongated pin 2| which extends within the restrictedsocket 22 in the base of the socket l9.

Surrounding this pin 2| and interposed between the keeper I! and theinner end of the socket 22 is an expansible member 23, herein disclosedas a coiled spring. This spring 23 constantly urges the keeper l1outwardly and in contact with the shoulder [6, so that normally thehandle member 9 is in such position with respect to the handle member Mto have the teeth 1 of the head 8 meshing with the teeth 6. However, asthe handle member 9 is swung outwardly, the spring 23 will allow thekeeper H to have the requisite downward or inward sliding movement.

The shank 4 of the jaw member A carries a spring-pressed ball keeper 24which normally extends slightly beyond the inner face of the shank 4 andis adapted to be selectively received within the slight depressions orindentures 25 in the inner face of the shank l of the jaw member B, tohold the jaw members A and B against separating movement after initialor quick adjustment, thus facilitating the desired coaction of the teethI of the handle member 9 with the teeth 6 of the shank I of thej e ber Bwhen desired to make the further finer adjustment to effect tightclamping hold on the Work between the gripping jaws 2 and 3.

From the foregoing description it is thought to be obvious that a plierwrench constructed in accordance with my invention is particularly welladapted for use by reason of the convenience and facility with which itmay be assembled and operated.

What is claimed is:

A plier wrench comprising two jaw members each comprising an elongatedshank and a gripping jaw extending laterally from one extremity thereof,the gripping jaw of one member coacting with the gripping jaw of theother member, means for maintaining the shanks of the jaw members insuperimposed relation with one of the jaw members having movementlengthwise of its shank along the other, said last shank being providedalong its inner face with teeth, a handle member pivotally engaged withthe outer end portion of the shank of the second jaw member, the pivotedportion of the handle member having teeth for engagement with the teethof the shank of the first jaw member, said teeth'being substantially toone side of the pivotal connection between the handle member and itsshank, the outer end face of the pivoted handle being rounded and onsuch radius that the said rounded face is free of the teeth of the shankof the first jaw member when the handle member is swung to apredetermined extent ir one direction, and a springpressed keeper setinto a recess in that end of the shank of the second jaw member whichopposes said rounded face,. the pivoted portion of the handle member atthe outer extremity of the curved end face being provided with ashoulder with which the spring-pressed keeper engages.
